Hmm well the cheepest 3ware RAID 5 SATA card is about =A3240 which is lik= e =A3100 more than my budget would strecth too, shame those 3ware cards look real = nice. Also I think they are 64bit pci, i only have 32bit pci :-( Im guessing that mmy best bet then is to get some sort of supported SATA controller and then to use Vinum on top to do the RAID stuff. Can anyone = make a well supported but under =A3140 recommendation. Shame coz those promise ones look wicked and fit my budget. Can anyone tell me how difficult it would be to develop a driver for the = promise card, I have experience of C and C++ amongst others and am fairly knowled= gable about PC's and Hardware but have never had to look so low-level as writti= ng a driver.
